Can the quantity and quality of human resources replace each other?

The quantity of human resources refers to the number of employees, and quality refers to the labor skills of employees. In some cases, they are interchangeable.

In various industries, there are many substitutes for the quantity of human resources by high-quality talents. For example, in a manufacturing enterprise, workers on the assembly line need ten people when they are unskilled, and only eight people when they are skilled, that is, quality replaces quantity.

Another joke: national football players are often satirized, such as "three midfielders are not as good as one Puyol" and "one Buffon is worth the whole defense line of China".
